What the formula actually does
Each row says where it comes from: F means we derived it from this product’s own ingredient list, S means it is a claim the brand makes that the formula neither confirms nor contradicts.
Nothing here is built to reduce combing force.
Oils are present, but low enough to be a finishing touch.
Humectants near the top — water-binding is a headline mechanism here.
Nothing here needs a detergent wash to remove.
Fragrance is listed; it sits below the working ingredients.
Ingredients that matter
The workhorse ingredients plus anything lower down that changes a decision. These chips name what an ingredient does — they are not safety scores, and no ingredient here is rated good or bad on its own.

US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.
The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.
Listed in the first three ingredients, it is likely a structural part of this formula.
A small water-loving molecule that draws moisture into the hair and holds it there. It is the most common softening ingredient in conditioners and leave-ins.
Listed in the first three ingredients, it is likely a structural part of this formula.
High-porosity hair loses water fast; a humectant holds some of it in place for longer than the wash itself would.
Binds water into the outer layers of the strand, and water is what makes dry hair flexible again rather than brittle.
Water moves both ways. Measured across concentrations, glycerin solutions give water up in some conditions and take it from the air in others. What it does for you depends on how much of it is there and on the air around it.
Provitamin B5. It draws in water and penetrates the strand a little, which is why it is the standard ingredient for softness and shine claims.
Listed in the first three ingredients, it is likely a structural part of this formula.
It hydrates without adding oil or a film, which is the combination fine hair usually needs.
Deposits a lubricating layer that makes combing easier, which is most of what stops mechanical damage adding to frizz.
A humectant that also penetrates the cuticle, so it holds water inside the strand rather than only on the surface.
Aloe gel, used for light moisture and slip. High in the list it also contributes a little natural hold.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
Gums thicken and set soft, which gives definition that bends rather than a rigid cast.
Hydration with no oil attached, so it adds very little weight even high on a list.
Aloe is mostly water carrying sugars that bind more of it, which is why it turns up as the base of moisture-first formulas.
A fermented sugar gum that thickens water-based formulas and adds soft, natural hold.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A polysaccharide film stays softer than a synthetic one as it dries, which is what leaves a curl defined but still able to move.
A soft film binds neighbouring strands together, which is most of what keeps flyaways lying down without stiffness.
Gum films stay soft. A style that needs firm fixation usually wants a synthetic polymer doing the holding.
An extract of Malus Domestica. Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
An extract of Grape (Vitis Vinifera). Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.
Listed in positions 4–8, it likely makes a meaningful contribution alongside the formula's main ingredients.
A light, widely used oil that softens without much weight.
Lower in the ordered portion of the list, it is more likely playing a supporting role than defining the formula.
Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.
A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.
It works on the surface. In the comparison that established coconut oil's penetration, sunflower oil did not reduce protein loss from washing — its fatty acids are bulkier and less linear. It softens and smooths; it does not reinforce the fibre.
A light plant protein that adds body and shine, popular in volume products.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Filling surface gaps evens out the cuticle, which is part of what makes damaged hair comb and reflect light more like undamaged hair.
Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.
Hydrolysed fragments are small enough to sit in the gaps of a worn cuticle for a wash or two, temporarily restoring stiffness and cutting breakage in combing.
An undisclosed blend of scent ingredients. Regulations let it stay unlisted, so a fragrance-free product is the only way to be certain what is not in it.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.
A soy- or sunflower-derived lipid that helps conditioning ingredients spread evenly on the strand.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
A thickener that turns a liquid into a clear gel. It also contributes a light hold.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
A set polymer film is a physical barrier to humidity, so a style keeps its shape longer in damp conditions.
Synthetic film formers dry into a continuous film, which is what holds a shape against movement and against humid air.
Some acrylate copolymers rinse with water and some need a detergent; the label alone does not say which one a formula used.
A preservative booster that also adds a little softness. Almost always paired with phenoxyethanol.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.
Patchouli essential oil, used as an earthy fragrance note.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Essential oils are fragrance. Several carry constituents on the EU list of declared fragrance allergens, so a label with no fragrance line can still be a scented product.
Cedarwood essential oil, used as a woody fragrance note.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.
Essential oils are fragrance. Several carry constituents on the EU list of declared fragrance allergens, so a label with no fragrance line can still be a scented product.
The essential oil of Ylang Ylang (Cananga Odorata). Essential oils are aromatic — they are in the formula for scent, and they are a common source of declared fragrance allergens.
It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

Price · 2.1 oz
Usually a good value. Most stores sell it under the $30 line, and products that do this job typically go for about $50 at this size.
Sorted by price per ounce. Dated observations from our research, not live prices. Direct store pages, no affiliate links. We don’t sell this product.
Formula
It costs about what other scalp treatments cost per ounce, but the formula leaves out conditioning agents up front, which most of the format carries.
The formula score is completeness for the job: the share of the systems this product type is normally built around that we can find in this list, weighted. It is not efficacy, not quality, and it never compares across product types.
Does the same job, for less
Same derived functions — what it cleans, conditions, coats or holds — at a lower cost per ounce. Scent, texture and where you buy it can still differ.

Claims check
Claims are quoted from the brand. We only mark one supported, partly supported, or conflicting when the ingredient list actually speaks to it; everything else stays "stated by the brand", which is not a criticism — most claims simply cannot be read off a label.
